Clarity lens technology controls the colour spectrum and is fine-tuned for use on the trail, sharpening green and brown associated with this riding environment, while also providing complete UV protection. A Ri-Pel lens treatment protects against dirt, oil and water and the anti-scratch coating ensures that your vision is always at its best. The lenses are easy to change and an extra clear lens is included, making the sunglasses ideal for use in many different riding conditions.
